Climate change cut global farming productivity 21% since 1960s

A Cornell-led study found that climate change has slowed global agricultural productivity growth by 21%, or about seven years, since the 1960s. The research used an econometric model linking weather changes and productivity measures to quantify the impact of human-caused climate change on total factor productivity.

How Fortnite and Zelda can up your surgical game (no joke!)

A study by a University of Ottawa medical student found that video games can improve surgical skills, particularly in robotic surgery and laparoscopic procedures. Games like Super Monkey Ball and Half Life were associated with improvements in time to completion, economy of motion, and overall performance.

Study finds why some cancer drugs may be ineffective

A study found that human tumor cells in patient-derived xenografts (PDX) are often compromised by mouse viruses, leading to false-positive results for cancer drug efficacy. The researchers analyzed 184 data sets and found that 170 samples showed the presence of mouse viruses.

GoPro HERO13 Black records stabilized 5.3K video for instrument deployments, field notes, and outreach, even in harsh weather and underwater conditions.

Possible trigger for Crohn's disease identified

A study led by McMaster University identified adherent-invasive E-coli (AIEC) as a strong potential trigger for Crohn's disease. AIEC bacteria are often found in the intestines of people with Crohn's, and research suggests that they can cause the condition by allowing them to freely colonize the gut lining.

Different general anesthetics affect consciousness and memory in different ways

A study published in PLOS Biology found that different general anesthetics have varying effects on the brain's hippocampus, a region essential for memory formation. Isoflurane resulted in undisrupted memory formation in mice, while other anesthetics caused significant changes in brain activity and stability of synaptic connections.

Apple iPhone 17 Pro delivers top performance and advanced cameras for field documentation, data collection, and secure research communications.

Telemedicine improves access to high-quality sleep care

A recent update from the American Academy of Sleep Medicine highlights the benefits of telemedicine in providing safe and effective sleep care. The use of telemedicine has improved adherence to CPAP therapy for obstructive sleep apnea patients, while cognitive behavioral therapy for insomnia shows similar results to in-person treatment.

Weight loss changes people's responsiveness to food marketing: study

A new study by UBC Sauder School of Business found that people with obesity tend to be more responsive to food marketing, but when their weight drops significantly, so does their responsiveness. After significant weight loss, people become less responsive to marketing, making it more sustainable to remain at a lower body mass index.

SLAS Technology April issue dives into reactive oxygen species

The April issue of SLAS Technology explores the therapeutic potential of reactive oxygen species (ROS) in applications ranging from wound healing and hair growth enhancement to cancer treatment and stem cell differentiation. However, limitations in controlling the temporal pattern of ROS release hinder their clinical translation.

SAMSUNG T9 Portable SSD 2TB transfers large imagery and model outputs quickly between field laptops, lab workstations, and secure archives.

Genome sequencing shows coronavirus variation drives pandemic surges

A new study from the University of California, Davis, found that COVID-19 cases are driven by emerging coronavirus variants. The researchers developed a metric called GENI to measure virus variation and its link to transmission rates, showing effective control of spread with measures like lockdowns and mask mandates.

Sony Alpha a7 IV (Body Only) delivers reliable low-light performance and rugged build for astrophotography, lab documentation, and field expeditions.

Diversity can prevent failures in large power grids

Researchers at Northwestern University found that heterogeneity in power grid frequencies leads to faster stabilization when generators are damped by breakers at different rates. This discovery could improve stability and design of future grid systems.

A new state of light

Researchers at the University of Bonn have discovered a new phase transition in an optical Bose-Einstein condensate of light particles. The overdamped phase exhibits unique properties that could be used to transmit quantum-encrypted messages between multiple participants.

Baby aspirin linked to lower risk of colorectal cancer death

Regular use of baby aspirin before a diagnosis of non-metastatic colorectal cancer is associated with better survival outcomes. The study found that low-dose aspirin use limits the spread of cancerous tumors pre-diagnosis, leading to lower death rates from the disease.

Mimes help us 'see' objects that don't exist

Researchers discovered that mimes can rapidly and automatically build representations of invisible objects in the mind. Participants responded significantly faster when implied surfaces aligned with the mimed action, indicating active mental representation. This finding has implications for artificial intelligence related to vision, su...

Apple Watch Series 11 (GPS, 46mm) tracks health metrics and safety alerts during long observing sessions, fieldwork, and remote expeditions.

Melting ice sheets caused sea levels to rise up to 18 metres

A recent study by Durham University reveals that the rapid sea-level rise at the end of the last ice age was primarily caused by the melting of ice sheets in North America and Scandinavia. This finding, which challenges previous theories, provides valuable insights into the complex interactions between ice-ocean-climate systems.

Landslides: New early warning systems reduce false alarms
